Re: Ammonia consumption
Hi, RANGER1 ... thanks ...
been busy around house and family ... one son with his family moved into new house (rebuild old one) and there were never ending requests for help since spring time ... another son moved back to our house ... again repairs, improvements, paintings ... 12 hours a day shift ... and still not finished, but winter is coming and some works we have to postpone until next year spring or summer ....
It is not a common thing ... more exception ... can be effect due to lack of good relief valves pressure test .... poor quality reliefs ... for some reason running plant at high discharge pressure ... some reliefs are equipped with handle for manual operation for check and maybe not close tight after check or just be opened by accident during installation without note to supervisor (to retest relief) ... new plant ... maybe young operators without a lot of experience ... etc .. kind of Murphy's law ...
... as I remember happened to me only on two plants (each with only one relief passing, but all were connected to common header going over roof and not quite good for access) so it is not so common but can happen ...
Best regards, Josip
It's impossible to make anything foolproof because fools are so ingenious...
Don't ever underestimate the power of stupid people when they are in large groups.
Please, don't teach me how to be stupid....
No job is as important as to jeopardize the safety of you or those that you work with.
